#890: Base library build fails with detailed build reporting

---------------------------------+------------------------------------------
If you turn on detailed build reports with `--build-log=foo.log` then
cabal-install uses the external setup method for a package rather than the
internal setup method.
If you try to use the external setup method with the "base" package then
compiling the setup executable like this fails:
{{{
/usr/bin/ghc -v --make ./dist/setup/setup.hs -o ./dist/setup/setup -odir
./dist/setup -hidir ./dist/setup -i -i. -package-conf
/Users/mbolingbroke/Programming/Checkouts/hackage-server/hackage-build
/build-cache/local.conf.d -package Cabal-1.10.2.0
}}}
The reason is that the base package exports a Prelude module which is
erroneously picked up when compiling Setup.hs in preference to the Prelude
exported by the installed base library. This manifests as:
{{{
*** Chasing dependencies:
Chasing modules from: *dist/setup/setup.hs
Prelude.hs:38:2: lexical error at character 'i'
}}}
(Because the Prelude in the base module uses CPP)
